Robust and comfy
I sized these the same as all of my other Patagonia stuff and they fit perfectly (I'm 5'10, 155#, 28ish waist). I went with the size 30 for layering and mobility. They have held up fine hiking around, climbing on all types of rock (granite, limestone, sandstone, etc.) and they still look brand new. They give me great range of motion and fit cleanly under my harness.
